Diagnostic testing or analysis of elements of network devices

ABSTRACT

Extensive resources can be required to stage, clean-and-screen, repair, diagnose, etc. a network device. To reduce the impact on resources, a diagnostic device is used to perform diagnostic testing or analysis of a network device, such as a set top box received at a facility. The diagnostic device connects to the network device via one or more connections to initiate a diagnostic testing and analysis. The network device sends diagnostic data to the diagnostic device which uses this data to generate a diagnostic report and/or sends this data to a network resource. The diagnostic testing or analysis is used to appropriately direct the network device, for example, for repair, redistribution, disposal, or other treatment.

BACKGROUND

Many service providers supply network devices to users, such as customer or entities. These network devices routinely require analysis to determine functionality. For example, network devices returned to a facility traditionally require labor and time intensive diagnostic testing or analysis to determine the functionality of the network device. This testing or analysis can indicate whether a network device should be refurbished or reprogrammed, scrapped, and/or repaired. However, traditionally this testing or analysis only returns a binary result without indicating any details associated with the testing or analysis and generally requires extensive resources including manual intervention. Thus, there is a need to expedite the processing of network devices to reduce costs and increase productivity.

SUMMARY

As described herein is a network and method for performing diagnostic testing or analysis to determine the functionality of one or more network devices. A considerable amount of resources can be expended per network device on staging, processing (such as clean-and screen), diagnostics, repair, and/or any other analysis. Reducing the required resources (such as time, man-power, incorrect redirection based on inadequate, incomplete, or false information, etc.) would increase productivity and decrease expenses. For example, a network device that is returned from a facility after being previously deployed and/or a new network device can be processed at a facility to direct the network device appropriately. Typically this processing fails to adequately diagnose issues with the network device and strains resources due to time for processing and manual steps. Delays in processing create deployment issues that impact for example, customer relations, profitability, costs, etc. Further, typical processing does not provide reliable identification of potential or actual issues with the network device. By providing a diagnostic device that performs a robust diagnostic testing or analysis of one or more elements of each of the network devices, resources can be conserved. For example, the network device is booted with minimal dependencies to ensure functioning of one or more elements of the network device and a reliable diagnostic testing or analysis is performed such that the time to evaluate or perform diagnostics on a network device is reduced while any issues or failures in functionality are quickly identified such that the network device can be expeditiously directed for appropriate handling. The diagnostic device can be connected to one or more network devices via one or more distinct connections so as to provide a comprehensive diagnostic testing and analysis of each of the connected network devices. The diagnostic device can ensure that any sensitive and personal data is wiped or cleaned from the network device prior to directing the network device, for example, to be refurbished, repaired, restocked, redeployed, etc.

FIG. 4 is a flow diagram for initiating a diagnostic testing or analysis of a network device 104, according to one or more aspects of the present disclosure. A network device 104 can be tested or analyzed to determine the functionality of one or more elements (such as one or more elements 311) of the network device 104. The testing or analysis can identify the one or more elements that do not meet a criteria or a threshold and can also indicate the reason or data associated with the one or more elements.

To begin, the diagnostic device 102 can establish at 402 a connection with the network device 104. A connection can be established via one or more interfaces, one or more connections to one or more connectors of the network device 104, any other connection, or any combination thereof. The establishing the connection 402 can include one or more physical or wireless connections between the diagnostic device 102 and the network device 104 and execution of an authentication routine, software, or program. For example, if the network device 104 is able to be powered on, the connection to the diagnostic device 102 can trigger the execution by controller 208 of an authentication of the diagnostic device 102. The network device 104 can send the diagnostic device 102 an authentication code or otherwise indicate that the connection is established and that the network device 104 is in a diagnostic mode. Authentication prevents the network device 104 from inadvertently switching from a normal operational mode to a diagnostics mode. In one or more embodiments, the network device 104 can be placed in or switched to the diagnostic mode by a key sequence, such as a sequence of any of one or more bits, one or more packets, one or more signals, any one or more other indicators, or a combination thereof sent from the diagnostic device 102 to the network device 104 via any one or more connections 114, a predetermined voltage at one or more connectors 214, any other sequence, or a combination thereof. In one or more embodiments, the network device 102 loads a rescue image 211, a programmable rescue image 217, a program image 215, or any combination thereof to perform the authentication.

Once the connection is established and the network device 104 is placed in a diagnostic mode, the diagnostic device 102 can send a request at 404 to network resource 160 for an image 122. The request can include a request for a diagnostic image, such as an image 122 for downloading to a network device 104 as diagnostic image 205, one or more identifiers associated with network device 104 (such as any of a serial number, a make, a model, a hardware version, a software version, any other identifying information, or a combination thereof), a timestamp, any other information, or a combination thereof. The diagnostic device 102 can receive at 408 the image 122 from the network resource 160. The diagnostic device 102 can send at 410 the image 122 to the network device 104. The image 122 can be stored as diagnostic image 205 in memory 206 of the network device 104. In one or more embodiments, the diagnostic image 205 can be local to the network device 104, such as stored as a program image 215B and loaded into memory 206 by boot loader 213, for example, when the network device 104 is placed in a diagnostic mode. In one or more embodiments, the diagnostic device 102 has the image 122 stored locally in memory 120 and does not require communication with the network resource 160.

The sending the image at 410 can cause the controller 208 to execute the one or more instructions associated with the diagnostic image 205. In one or more embodiments, the diagnostic device 102 can send a sequence of one or more bits or an instruction that causes the controller 208 to execute the one or more instructions of a diagnostic image 205 stored in memory 206. At 411, the controller 208 can execute the one or more instructions for the diagnostic testing or analysis of one or more elements of the network device 104. In one or more embodiments, at 411, the network device 104 can, for example, initiates a test 310 that causes the diagnostic device 102 to respond with a signal directed to the network device 104 whereupon the network device 104 generates report data, such as data indicative of a detection of the signal. For example, the network device 104 can initiate a test at a network port or connector of the network device 104 by sending an instruction to the diagnostic device 102 that causes the diagnostic device 102 to send a signal to the network port or connector and/or data associated with the test 310 is generated by the network device for communication to the diagnostic device 102 as diagnostic data 207. As another example, the diagnostic device 102 can initiate one or more simulations, such as the diagnostic device 102 simulating a television connected to the HDMI connector or port 214, that sends a signal to the network device 102 and whereupon a diagnostic report 124 is generated and/or data is collected and sent to a network resource 160 by the diagnostic device 102 based on a response or lack thereof from the network device 104.

The diagnostic device 102 receives at 412 diagnostic data 207 from the network device 104. The diagnostic data 207 can include information associated with an element 311 and corresponding status 313 or any other information associated with the diagnostic testing or analysis of the network device 104. The diagnostic data 207 can be sent from the network device 104 to the diagnostic device 102 in real-time, periodically, routinely, at the request of the diagnostic device 102, or any combination thereof.

The diagnostic device 102 sends at 414 a diagnostic report 124 to the network resource 160. In one or more embodiments, the diagnostic report 124 can be stored locally at the diagnostic device 102 in memory 120. The network resource 160 can process the diagnostic report 124, one or more additional criteria (such as thresholds, specifications, or other information associated with the network device 104, or any combination thereof), any other data, or any combination thereof. The diagnostic device 102 can receive at 416 one or more output results from the network resource 160. The one or more output results can indicate how the network device 104 should be directed. For example, the one or more output results can indicate that the network device 104 is not functioning and needs to be sent for repair or scrapped, operational, requires one or more updates to hardware, software, or both, any other indication, or any combination thereof. The diagnostic device 102 can send the one or more output results at 418 to the display device 170, any other computer system, or both. The network resource 160 can store the diagnostic report 124 for later retrieval, such as for generating one or more statistics associated with the diagnostic testing or analysis of one or more network devices 104.

After performing the diagnostic testing or analysis, the diagnostic device 102 can request at 420 an image 122 from the network resource 160. The request can be for an image 122 associated with a disaster recovery image (such as a rescue image 211), a programmable disaster recovery image (such as programmable rescue image 217), a program image 215A (such as a diagnostic image 205, a factory flash image, system software, any other image, or any combination thereof), any other image, or a combination thereof. The diagnostic device 102 can receive at 422 the image and then send at 424 the image to the network device 104 for storing in memory or non-volatile storage 212. In one or more embodiments, the image can clear any previously stored information in memory 206, memory or non-volatile storage 212, or both. For example, the network device 104 can be directed to be scrapped and the image can be downloaded to the network device 104 to clear or wipe (for example, a clean-and-screen process) any personal user information from the network device 104, such as any image or data in a programmable flash memory.

FIG. 5 is a flow diagram for performing diagnostic testing or analysis of a network device 104, according to one or more aspects of the present disclosure. As similarly discussed with FIG. 4 , a connection is established at 502 between the network device 104. For example, a controller 208 (such as a central processing unit (CPU)) of the network device 104 can authenticate the connection. The network device 104 can receive at 504 diagnostic image (such as an image 122) from the diagnostic device 102 as a diagnostic image 205 and the controller 208 can execute at 506 the diagnostic image 205. In one or more embodiments, after the connection is established, the controller 208 can load into memory 206 a program image 215B as the diagnostic image 205 from a memory or non-volatile storage 212. The program image 215B can be updated by the received diagnostic image 205 at 504 or executed in lieu the diagnostic image 205 at 504. The controller 208 can send at 508 a validation of the diagnostic image 205 to the diagnostic device 102, for example, a checksum or any other indication that the diagnostic image 205 is executable by the network device 104.

To begin the diagnostics analysis or testing of the network device 104, the controller 208 can receive at 510 a diagnostics command from diagnostic device 102. The diagnostic command can initiate one or more specific tests associated with the execution of the diagnostic image 205, initiate the sending at 512 of diagnostic data 207 associated with the execution of the diagnostic image 205, or both. In one or more embodiments, the diagnostic command can be a USB EXEC command. In one or more embodiments, the controller 208 initiates execution of diagnostic image 205 and sending at 512 of diagnostic data 207 without receiving a command from the diagnostic device 102.

After completion of the diagnostic testing or analysis, for example, execution of the diagnostic image 205 has completed, the program image 215A can be received at 514 by the network device 104 and the controller 208 can load at 516 the program image 215A to verify the operability of the program image 215A. The controller 208 can send a validation to the diagnostic device 102, for example, as part of or included with diagnostic data 207. In one or more embodiments similar to FIG. 4 , the program image 215A can clear any previously stored information in memory 206, memory or non-volatile storage 212, or both. Similar to FIG. 4 , the diagnostic device 102 can send the one or more output results to the display device 170. As discussed with FIG. 4 , in one or more embodiments, the diagnostic device 102 can send the diagnostic report data to a network resource 160, the network resource 160 can generate a diagnostic report 124 that is sent to the diagnostic device 102, and the diagnostic device 102 can output the diagnostic report 124 to the display device 170. In one or more embodiments, the display device 170 is coupled to the network resource 160 and the network resource 160 outputs the diagnostic report 124 to the display device 170. For example, the diagnostic report 124 can be output to the display device 170 as a web page in a web browser.

FIG. 6 is a flow diagram for initiating, for example, automatically, a diagnostic testing or analysis of a network device 104, according to one or more aspects of the present disclosure. A diagnostic device 102, a network device 104, a network resource 160 may be programmed with one or more computer-readable instructions that when executed by a controller or processor cause one or more operations according to FIG. 6 . In FIG. 6 , it is assumed that any one or more of the devices include their respective controllers and their respective software stored in their respective memories, as discussed above in connection with any of FIGS. 1-5 , which when executed by their respective controllers perform the functions and operations in accordance with the example embodiments of the present disclosure (for example, including performing a configuration of one or more network devices). While the steps S602-S612 are presented in a certain order, the present disclosure contemplates that any one or more steps can be performed simultaneously, substantially simultaneously, repeatedly, in any order or not at all (omitted).

A diagnostic analysis of a network device 104 can be initiated at step S602 by authenticating a connection to a diagnostic device 102. For example, a network device 104 can be received at a facility that includes a network, such as a network 100 of FIG. 1 . The network device 104 is coupled to or otherwise placed in communication with a diagnostic device 102. The diagnostic device 102 can attempt to establish a connection to the network device 104, for example, via a wired or wireless connection, such as via a Wi-Fi and/or via a connection between a connector 140 and a connector 214 so as to establish a connection 114. In one or more embodiments, the authentication is based on the network device 104 receiving a boot loader key sequence from the diagnostic device 102, for example, to cause a programmable rescue image 217, such as a programmable disaster recovery image (PDRI), a diagnostic firmware image, a production firmware image (including, for example, a firmware image constructed using a reference design kit (RDK), an Android framework, a Windows framework, any other framework, etc.), any other firmware image, or any combination thereof, to be loaded by the boot loader 213 into the memory 206 from a memory or non-volatile storage 212 so as to perform the authentication. For example, the programmable rescue image 217 can be a production firmware image loaded during end-user or customer use of the network device 104. In one or more embodiments, a secure sockets layer (SSL) certificate is received from the diagnostics device 102. The SSL can then be verified by the network device 104 against a root certificate authority (CA) certificate, for example, stored in a memory or non-volatile storage 212 of the network device 104. The network device 104 can send a certification, such as any of a validation, a verification, an authentication, or any combination thereof, to the diagnostic device 102. In one or more embodiments, the diagnostic device 102 receives a certificate, the SSL certificate or any other certificate, from a network resource 160 and the authentication with the network device 104 is based on the received certificate.

Once the authentication has been performed, at step S604 the network device 104 can load a diagnostic image 205, for example, based on receiving a key sequence or a key in addition to any key sequence or initiation started at step S602. For example, the network device 104 can receive a special key sequence from the diagnostic device 102 that causes, for example, the boot loader 213 to load a program image 215B from memory or non-volatile storage 212 as a diagnostic image 205 in memory 206. In one or more embodiments, an image 122 can be received from the diagnostic device 102 and loaded into memory 206 as a diagnostic image 205. In one or more embodiments, the diagnostic device 102 can receive the image 122 from a network resource 160.

At step S606, a diagnostic analysis or testing is performed based on the diagnostic image 205. In one or more embodiments, the diagnostic image 205 is an image 122 downloaded from the diagnostic device 102, a program image 215 loaded from a memory or non-volatile storage 212, or both. The diagnostic analysis or testing can include the testing or analysis of one or more elements 311A associated with a hardware test 310A, one or more elements 311B associated with one or more software tests 310B, or both. In one or more embodiments, the performing the diagnostic analysis or testing is based on a diagnostics initiation command that is received from the diagnostic device 102. For example, the diagnostic initiation command can cause the controller 208 to initiate or execute the one or more computer-readable instructions associated with the diagnostic image 205 such that the diagnostic analysis or testing is initiated or performed. The diagnostic initiation command can be the same as or similar to the diagnostics command at 510 of FIG. 5 . The diagnostics initiation command can comprise a plurality of commands, such as one or more commands generated from a script executed by the diagnostic device 102. In one or more embodiments, the diagnostics analysis or testing comprises a clean-and-screen process or similar process that clears or wipes data, such as user data, customer data, personal data, any other data, or a combination thereof, from the network device 104.

In one or more embodiments, the diagnostic analysis or testing of step S606 can comprise detecting a status 313 of an element 311 associated with a test 310, for example, as discussed with reference to FIG. 3 , and generate the diagnostic data 207 based on the status 313. The diagnostic data 207 from the test 310 can be any of generated as a diagnostic report (such as diagnostic report 300), stored in memory 206 as a diagnostic data 207, transmitted to the diagnostic device 102, the network resource 160, or any other storage medium, or any combination thereof.

At step S608, diagnostic data is sent from the network device 104 to the diagnostic device 102. The diagnostic data 207 is based on the diagnostic analysis performed in step S606. The network device 104 can store diagnostic data as diagnostic data 207 in a memory 206 and can send the diagnostic data 207 to the diagnostic device 102 in real-time, periodically, routinely, at the request of the diagnostic device 102, or any combination thereof.

At step S610, a program image 215 is received from the diagnostic device 102 based on the diagnostic data 207 provided in step S608. For example, the diagnostic device 102 can determine that the network device 104 is functional or operational and can download an image 122 as a program image 215 to the network device 104. The program image 215 can comprise a PDRI, a RDK, a FFI, any other image, or a combination thereof.

At step S612, the connection (such as a wired connection, a wireless connection, or both) between the network device 104 and the diagnostic device 102 is disconnected. The network device 104 can then be directed appropriately, for example, based on a diagnostic report 124 generated based on the diagnostic data 207. For example, the network device 104 can be directed to a refurbishment facility for repairs of one or more elements 311 as identified by an associated status 313 in the diagnostic report 124, a shipment facility for redeployment into the field or other site, a recycling or other waste management facility, or any other facility, department, or storage area.

FIG. 7 is a flow diagram for a diagnostic device 102 to initiate, for example, automatically, a diagnostic testing or analysis of a network device 104, according to one or more aspects of the present disclosure. A diagnostic device 102, a network device 104, a network resource 160 may be programmed with one or more computer-readable instructions that when executed by a controller or processor cause one or more operations according to FIG. 7 . In FIG. 7 , it is assumed that any one or more of the devices include their respective controllers and their respective software stored in their respective memories, as discussed above in connection with any of FIGS. 1-5 , which when executed by their respective controllers perform the functions and operations in accordance with the example embodiments of the present disclosure (for example, including performing a configuration of one or more network devices). While the steps S702-S712 are presented in a certain order, the present disclosure contemplates that any one or more steps can be performed simultaneously, substantially simultaneously, repeatedly, in any order or not at all (omitted).

A diagnostic analysis of a network device 104 can be initiated at S702 by authenticating a connection to a diagnostic device 102. For example, authentication can occur as discussed with reference to step S602 of FIG. 6 . In one or more embodiments, the diagnostic device 102 exchanges a certificate with the network device 104. The diagnostic device 102, can receive an acknowledgement from the diagnostic device 102 that the diagnostic device 102 is recognized or otherwise authorized to place the network device 104 in diagnostic mode or to cause initiation of a diagnostic test or analysis. In one or more embodiments, the diagnostic device 102 connects to the network device 104 via a plurality of connections, for example, a first connection of the plurality of connections is a wired connection and a second connection of the plurality of connections is a wireless connection.

At step S704, the diagnostic device 102 sends a diagnostic command to the network device 104, for example, a diagnostic command as discussed at 510 of FIG. 5 . The diagnostic command can comprise an instruction, a key sequence, a script, any other command that causes the network device 104 to initiate a diagnostic testing or analysis. At step S706, the network device 104 initiates a diagnostic test or analysis of the network device 104 based on the diagnostic command. At step S708, the diagnostic device 102 receives diagnostic data 207 from the network device 104. At step S710, the diagnostic data 207 is used to generate a diagnostic report 124. In one or more embodiments, the diagnostic report 124 is generated based on information received from a network resource 160 and the diagnostic data 207. For example, the diagnostic data 207 can be sent to the network resource 160 by the diagnostic device 102 and the network resource 160 can send a diagnostic report 124 to the diagnostic device 102. The diagnostic report 124 can be generated based on identifying a status 313 of one or more elements 311 as indicated by the diagnostic data 207. For example, the diagnostic data 207 can indicate whether an element 311 is functional or non-functional (a status 313) including any additional data or information necessary to adequately indicate the results of the testing. For example, the diagnostic data 207 can indicate a reason for a failure or issue associated with an element 311. The diagnostic report 124 can be used to identify a condition of the network device 104 or how to direct the network device 104. In one or more embodiments, the program image 215 can be requested by the diagnostic device 102 from a network resource 160 based on the diagnostic report 124, information received from the network device 104, or both. For example, the diagnostic report 124 can indicate that the network device 104 is operational, functional, or otherwise usable by a user or customer such that the program image 215 is a production image or FFI and information received from the network device 104, for example, during authentication, can indicate one or more identifiers associated with the network device 104 such that the program image 215 is requested based on the one or more identifiers and any one or more values associated with the diagnostic report.

At step S712, the diagnostic device 102 is disconnected from the network device 104 and the network device 104 is appropriately directed based on the diagnostic report 124. In one or more embodiments, the diagnostic device 102 can output the diagnostic report 124 to a display device before or after disconnecting the network device 104.

In one or more embodiments, a network device 104 is returned to a facility, such as within a network 100 of FIG. 1 . The network device 104 can include a bar code or other identifier that can be scanned by any device within the network 100, for example, by a diagnostic device 102 so as to obtain any of a history, a version, a make, a model, any other identifying information, or any combination thereof of the network device 104. The network device 104 is connected to any of the network connection 150, diagnostic device 102, network resource 160, or any combination thereof and is powered-up. The network device 104 is connected to a diagnostic device 102 via a wired connection, a wireless connection, or both before and/or after being powered-up. The network device 104 can be placed in a diagnostic mode based on a special key sequence received from the diagnostic device 102 via the connection. In one or more embodiments, the key sequence requires a plurality of connections between the network device 104 and the diagnostic device 102. If the key sequence is successfully authenticated and the network device 104 is placed in the diagnostic mode, the boot loader 213 can load a program image 215 as a diagnostic image 205 in the memory 206, load an image 122 received from the diagnostic device 102 as the diagnostic image 205 in the memory 206, or receive the diagnostic image 205 from a network resource 160. Execution of the diagnostic image 205 by the controller 208 can cause one or more tests of one or more elements 311 associated with a test 310 to be performed and for diagnostic data 207 to be collected or generated. For example, a status 313 (such as a pass or fail) of an element 311 (such as a hardware element 311A or a software element 3111B) associated with a test (such as hardware test 311A or a software test 3111B) can be collected as diagnostic data 207. The diagnostic data 207 can be sent to a diagnostic device 102 and used to generate a diagnostic report 124. If the diagnostic report 124 indicates a failure or that one or more elements 311 meet, reach and/or exceed a threshold, the network device 104 can be directed to, for example, a refurbishment facility, a repair facility, or any other location, department, or site. The diagnostic report 124 can be stored in a network resource 160 such that the diagnostic report 124 can be accessed from any facility or location. For example, if the network device 104 is sent for repairs, the diagnostic report 124 can be accessed to identify the issue, such as the element 311, that requires repair, the repair needed, any other information, or a combination thereof.

In one or more embodiments, a network device 104 is received at a facility, for example, within a network 100. The network device 104 is loaded with a program image 215, such as a PDRI. The PDRI can be based on any kernel or framework, for example, a minimal Linux kernel built into the build-root environment. The PDRI can have a small flash footprint, boot quickly, and be easily customized. In one or more embodiments, the PDRI can be included as part of the FFI. The FFI can comprise a complete image of flash memory that can include the boot loader, DRI, PDRI, one or more production firmware images, a manufacturing test image, a diagnostic image, or any combination thereof. The FFI can be loaded directly onto a memory during assembly, for example a flash memory. A diagnostic device 102 can be connected to the network device 104 via one or more connections 114. The diagnostic device 102 can send a key sequence to the network device 104. The key sequence can be a boot loader key sequence that cause the boot loader 213 to load the program image 215 (such as a PDRI or DRI) into the memory 206. In one or more embodiments, diagnostic device 102 can send a test sequence key, in addition to or in lieu of the key sequence, to the network device 104 to cause the network device 104 to be placed in a diagnostic mode that allows for the diagnostic testing or analysis of one or more elements 311 of the network device 102. For example, the test sequence key can cause an image to launch in a diagnostic mode, for the program image 215 to cause the boot loader 213 to load a diagnostic image 205 (such as any of a program image 215, an image 122 from the diagnostic device 102, an image from a network resource 160, any other image, or a combination thereof). In one or more embodiments, the diagnostic image 205 is a diagnostic testing or analysis software, a clean-and-screen application, or any other testing software.

In one or more embodiments, execution of the diagnostic image 205 enables Ethernet for commutations with a back-end server, such a network resource 160. One or more dynamic host configuration protocol (DHCP) options, one or more configuration files, or both can be utilized by the diagnostic image 205 to determine one or more modes of operation for execution of the diagnostic image 205. For example, the one or more configuration files, the one or more DHCP options, or both retrieved from a remote resource 160, a diagnostic device 102, or both. The one or more configuration files can be download to the network device 104 via the diagnostics device 102 and/or any other device.

In one or more embodiments, the diagnostic image 205 initiates a hardware test 310A once the Linux kernel boots. The one or more elements 311A associated with the hardware test 310A can test the one or more hardware failures associated with the type of network device 104. For example, the diagnostic device 102 can determine the type of network device 104 based on information received from the network device 104 and initiate one or more tests 310 at the network device 104, such as by causing an image 122 associated with the type of network device 104 to be downloaded to the network device 104 as a diagnostic image 205. The controller 208 can execute the one or more computer-readable instructions associated with the diagnostic image 205 to test one or more hardware elements 311A for a hardware failure, such as any of a HDD failure, a flash failure, a SD card failure, a DOCSIS failure, a Wi-Fi failure, a MoCA failure, an LED failure, a cable modem failure, a video hardware failure, a failure associated with one or more connectors 214, any other hardware failure, or a combination thereof, and/or one or more software elements 311B for a software failure, such as any of a memory read failure, an interface failure, a checksum failure, any other type of software failure, or a combination thereof. Any one or more tests 310 can generate diagnostic data 207 which can be sent to a storage device, such as the diagnostic device 102, the network resource 160, any other storage medium, or a combination thereof and used to generate a diagnostic report 124. The diagnostic device 102, the network resource 160, or both can utilize the diagnostic report 124 to determine whether a network device 104 has passed or failed the diagnostic testing or analysis. If one or more elements 310 of the network device 104 do not pass or meet a threshold, the network device 104 can be directed to be repaired, refurbished, or otherwise processed. If one or more elements of the network device 104 pass or meet a threshold, the network device 104 can be processed for restocking or redistribution. For example, a program image 215, such as a clean-and-screen application, can be initiated by a key sequence from the diagnostic device 102 such that an update process is executed. The update process can include any of removal of one or more objects or data from the network device 104, loading one or more objects are data, downloading one or more images 122 as a program image 215, such as any of an updated PDRI, an RDKI, any other version of production image, or any combination thereof, any other update process, or any combination thereof. The network device 104 can send an update parameter to the diagnostic device 102 to indicate the success and/or failure of any portion of the update process. The update parameter can be stored as part of the diagnostic report 124. The determination whether to the redeploy the network device 104 can be based on the update parameter, any other part of the diagnostic report 124, or any combination thereof.

Techniques consistent with the present disclosure provide, among other features, systems and methods for a diagnostic testing or analysis of a network device 104 using a diagnostic device 102 so as to improve the diagnostic testing or analysis, for example, to improve the accuracy, reliability, results, or any other factors associated with a network device 104. For example, according to one or more embodiments discussed herein a network device 104 can be directed appropriately, such as for re-use, repair, disposal, any other use, or any combination thereof.
